Hi,

Yes, it is suitable for PS5. Connect your video game console with HDMI support to your TV using an HDMI cable. Use the HDMI cable supplied with the game console or an Ultra High-Speed HDMI™ cable. Press the (Quick Settings) button on the remote control and select the following in order.
[Settings] - [Channels & Inputs] - [External Inputs] - [HDMI Signal Format].
Select the optimum format for your video game console.

You can also connect the TV to a PC. Use an HDMI cable to connect a computer to the TV.
* Be sure to use an approved premium high-speed HDMI™ cable with the HDMI logo. We recommend an Ultra High-Speed HDMI™ cable for connecting to a computer with 4K 120 Hz support.
